srncrrrcn'rroiv forming part of Letters Patent No. 644,871, dated March 6, 1900.: Application filed August 14, 1896. Serial No. 602,755. (No model.)

To 04% whom it may concern:

Be it known that I, VERNON BOYLE, of Paterson; in the county of Passaic and State of New Jersey, have invented a new and useful.

Improvement in Piano-Machines for Pu nching Jacquard-Cards, of which the following is a specification.

My invention relates to an improvement in piano-machines for punching jacquard-cards,

and more particularly to that type of machine which is known in the art as a power-machineasdistinguished fromamachinedriven by the operator.

In the accompanying drawings, Figure 1 is a View of the machine in front elevation. Fig. 2 is a top plan view with pattern-support broken away. Fig. 3 is a side elevation, the side of the supporting frame or pedestal being removed to show the operating parts more clearly. Figs. 4t and 5 represent views in detail of the clutching mechanism in released and locked positions, respectively. Fig. 6 is a View in detail of a portion of the feed-carriage support, showing the feed-carriage and its connection with the support. Fig. 7 is a view in detail of the dogs for controlling the movement of the carriage, showing them in position upon their rock-shaft support.

Fig. 13 is a horizontal section through the carriage, taken on an enlarged scale through the plane of the teeth of the rack-bar, showing the parts below in top plan. Figs. 14 and 15 are partial end views of the carriage, showing the two positions which the rocking teeth for engaging therack-bar assume when their operating-shaft is swung to the limit of its rocking movement in each of two opposite directions. Fig. 16 is a h0rizontal section taken beneath the table (1?, and

] Fig. 17 is a bottom plan view of the apron o and the parts carried thereby. v

The machine comprises an operating wheel able source of power, a punching mechanism, an operating'shaft connected with the punching mechanism, means under the control of the operator for locking the operatingshaft to and releasing it from the continuously-driven pulley at pleasure, a feed mechanism under the control of the punching operating mechanism to feed the card at the desired intervals, a pattern-support mounted to assume such varying positions as may be desired and provided with means for determining at each step the exact position of the particular point in the pattern which is to be considered in punching the card, and in connection with the above-mentioned features several specific features of structure and arrangement, as will be hereinafter particularly described.

The pedestal or main supporting-frame consists of side plates A A, connected by a Web a and made flaring at the base. 4 The pedestal is supported upon yielding cushionssuch, for example, as ru bber(denoted by a) and at its top is provided with a table 0.2, from which an apron a projects toward the front.

A punching mechanism of any well-known or approved form is shown at B. It is supported by a pair of guide-rods Z) Z), which extend down through the table a and into sockets formed in lugs a a at the base of' the pedestal. The guide-rods Z) Z) are connected by a cross-piece 12 which is connected by an eccentric-rod b with an eccentric c on the drive-shaft G to impart to the punches the reciprocating movement when the shaft is rotated.

The drive-shaft C is mounted in an extended bearin g a,projecting rearwardly from the pedestal, and the continuously-driven pulley D for actuating the machine is mounted on the rear end of the shaft. The shaft 0 is clutched to and released from the pulley D as follows: Fixed to rotate with the shaft 0 are clutching-shoes E E, placed in the present instance diametrically opposite one another and attached to their supporting-wings e e by stems e (two for each shoe,) which permit the shoes to slide radially toward and or pulley, which may be driven from a suit-.

away from the inner curved surface of the rim (1 of the pulley D. The shoes are connected with a hub c", mounted to rock independently of the wings e c, by what I am pleased to call toggle-dogs e 6 Arms 6 and c radiate from the hub c and have their free ends connected by springs e e with fixed supports on the wings e e, the tension of the springs being such that when free to act they will rock the hub c in a direction to throw the toggle-dogs into or toward the radial lines from the position shown in Fig. 4 to the position shown in Fig. 5 to press the shoes E E simultaneously toward the rim of the pulley to clutch the shaft thereto. The hub c is positively rotated in the opposite direction to release the shoes from the pulley by means of an arm a which is operated by a nose or cam F, fixed to rock with a dog f, which is operated by a cam f on a sleeve f mounted to slide longitudinally on the shaft C. The free end of the arm 6 is connected by a spring e with the tail of the dog f. The sleeve f is slid along the shaft 0 to operate and release the clutch by means of a pair of foot-levers G G, fulcrumed on a hanger 9, depending from the bearing a and connected by rods 9 g with two oppositely-extending arms g of a tri-armed lever, the third arm g of which has its free end engaged with the said sleeve f The levers G and G are provided with adjustable stops g to limit their downward movements. In operation when the lever G is depressed, as shown in Fig. 3, the sleevef will be slid toward the front to bring the cam f out of the path of the dog J, and the shoes E E Will thereby be left free to clutch the pulley D to the shaft; but when the lever G is depressed the sleeve f will be slid into position to place the cam f in the path of the dog J" and it will be rocked into the position shown in Fig. 4, thereby forcing the hub e around against the tension of the springs c e and releasing the clutching-shoes, and hence the shaft 0, from the pulley.

The card is fed rearwardly step by step alternatelywith the operation of the punches as follows: A guide-bar H, forming a support and track for the feed-carriage I, projects rearwardly from the pedestal below the apron a In the present instance the bar H is cylindrical in cross-section and has fixed in its under side a rack-bar h. The body of the carriage I is simply a short sleeve fitted to slide smoothly along the bar H and provided with two pairs of uprising legs 11 z" and with depending legs 2' 1, which embrace a rock-shaft K, extending parallel with and spaced a short distance from the supportingbar H. On the rock-shaft K, between the legs 11 and t of the feed-carriage, there are located two short sleeves or collars 7c the former, 7c, fixed to the shaft K and the latter, is, caused, by means of the well-known feather-and-groove attachment or its equivalent, to rock with the shaft, but permitted to move a limited distance back and forth longitudinally of the shaft. The distance the part 70 is permitted to move is regulated by a nut 70 on a screw-threaded extension of the part 70, which causes the said part to be stopped by the leg i earlier or later, according to the position of the nut.

The sleeves or collars k 7c are each provided with a tooth, the former with a tooth 7t and the latter with a tooth located in different longitudinal planes through the axis of the shaft K, so that when one of the teeth is swung into position between two teeth of the rack-bar h the other will be out of engagement with the rack-bar. The collar or sleeve kl is held normally to the limit of its movement away from the part 70 by means of springs 70 inserted in sockets in the face of the part 70 and bearing against the face of the part 76.

The shaft K is rocked to bring first one and then the other of the teeth k k into engagement with the rack-bar by an angle-lever having a socket portion L for the reception of the end of the shaft at the front of the machine, one arm Z being pivoted to asleeve Z on a rod Z connected with an eccentric Z on the drive-shaft C, and the other arm Z being connected by a rod Z with a crank-arm Z on an operating-rod Z provided with a handle Z within convenient reach of the operator at the front of the machine. The sleeve Z is connected with the rod Z" by a spring Z", the tension of which is sufficient to cause the sleeve to reciprocate with the rod Z to rock the shaft K, butpermitting the shaft K to be rocked by hand by the rotation of the opcrating-rod Z without disturbing the rod Z, connected with the eccentric.

The feed-carriage is drawn constantly to the rear by means of a spring-actuated pulley M, to the periphery of which the ends of a cord m are secured, the bight of the cord passing about one of a vertical series of pulleys m, mounted on the upright arm m of an angle-lever pivoted at m to the carriage and having its forwardly-extending arm m loosely engaged with the tail of a grippingdog m pivoted to the carriage at m, with its gripping-jaw m in position to hold the rear end of the card being operated upon between it and a stationary jaw m at the front of the carriage. For relieving the sliding friction on the bar H, the carriage may be provided with rollers 2M set in position to sustain the weight of the carriage on the bar, the rollers i being set obliquely at the front of the carriage in a pair and the roller 2' being set upright in position to travel along the crown of the bar.

The grip of the dog m upon the card may be increased or diminished, while the spring tension remains the same, by shifting the bight of the cord m to an upperor lower pulley of the series m.

The pulley M is fixed to a shaft N, mounted in the branches of the bifurcated head 0, fixed to the rear end of the bar H. The shaft IIO N is held under spring tension by a pair of coiled springs n n, located upon opposite sides of the shaft-bearings 7 and having one end of each connected to a cross-bar 0, fixed to the head 0, and the opposite ends to the shaft N, or, as preferred, to sleeves n moun ted on the shaft N within the spring-coil and fixed to hand-wheels n, which may be locked to the shaft N by means of disks n the hubs of which are connected with the shaft N by the ordinary feather-and-groove or other equivalent means, the said hand-wheels n being forced into frictional gripping-contact with the disk n by hand-nuts 11 which work on screw-threaded portions of the shaft N and bear against movable disks a on the shaft at the opposite ends of the sleeves n from the hand-wheels n This structure admits of releasing the hand-wheel of either spring from the shaft N at-pleasureand then winding or unwinding the spring by turning the handwheel in one direction or the otherto getjust the most efficient amount of tension on the carriage to cause the escapement hereinabove particularly described to work to the best advantage. The feed-carriage is provided at its rear end with a plunger 2', which as the carriage nears the limit of its rearward movement enters a socket o in the head 0 and forms a compressed-air cushion, particularly when the carriage is permitted from any cause to travel back quickly to prevent injury from sudden stoppage.

The cards as they are drawn rearwardly by the carriage are supported upon wires 0 0*, leading from the opposite wings of a pivoted bracket 0 on the head 0 forwardly to the rear edge of the apron a A pair of laterally-sliding cheek-pieces P P are automatically drawn toward each other by link connections 19 p, with the opposite arms 10 10 of a lever pivoted to the table a at p, the arm 19 of the lever being connected with the table by a spring 19 which may be attached to the lever at different distances from its fulcrum to exert a greater or less tension upon the cheek-pieces. The limit of the movement of the cheek-pieces toward each other is determined by a pin 19 on a slide 13 which may be adjusted laterally of the table by a set-screw p thereby rendering it feasible to adjust the cheek-pieces to cards of different widths without changing the position of the center line between the pieces and leaving the pieces at all times free to be separated to insert a card.

The feed-carriage has attached thereto a cord '6 for drawing it forward into position to grip the end of a card. The same cord 11 passes over a pulley p on the cheek-piece P, so thatthe strain upon the cord to pull the carriage forward may be utilized to draw the cheekpieces apart for the insertion of a blank card between them.

As the shaft 0 rotates to operate the punches it rocks the shaft K over and back to bring the ratchet-teeth k 7.; into and out of engagement with the rack. Suppose the feed-carriage to be under strain from its actuating-pulley as the tooth is rocked out of engagement with the rack and the tooth 15 into engagementtherewith. The feed-carriage, together with thetooth k will move rearward against the tensionof the springs k until the sleeve or collar is, carrying the tooth 70 abuts against the sleeve or collar 70, carrying the tooth 70 at which point it will be arrested by the engagement of the tooth k with the rack on the bar H. When the shaft K is rocked back, the tooth k will engage the rack at a point farther to the rear, and as soon as the tooth 7r} escapes from the rack it will jump rearwardunder the tension of the springs into position to again arrest the rearward movement of the carriage when the tooth k is released. When the card has been punched and it is desired to return the feed-carriage to the front, the rod Z is turned by the hand of the operator, thereby rocking the shaft K sufficiently to throw the teeth k k out of engagement with the rack h, and the carriage is then drawn directly to the front by the cord The spring Z, connected with the sleeve Z will serve to rock the shaft K to bring the teeth [a 70 into the proper relation to the rack as soon as the handle Z is released.

The pattern which furnishes a guide to the operator in punching the cards is held spread before him on the face of a pattern-board Q. The board Q is provided with a pair of supporting-brackets q q, fixed to its back and hinged at their lower ends, as at g to a base-plate g to permit the board to be tilted forward and backward to assume the slant which is found most expedient for reaching the pattern. The board is adjusted in its various tilting or in its upright positions by means of a slotted link or brace (1 pivoted at its upper end to the bracket q and receiving through the slot in its lower end a set-screw for clamping it to the plate (1 The base-plate g is fixed in forward and backwardadjustment on the tops of a pair of standards (1 g by means of bolts (1 which extend through elongated slots (1 into the heads of the standards. The standards g (1 are bolted at their bases to the top of the pedestal A A. The board Q may also be bodily raised and lowered by means of the several half-sockets q arranged in diif'erent vertical positions and each adapted to receive the pintle of the hinge at 1 A double rule consisting of the parallel bars R R, fixed to end pieces rr', is attached to the pattern-board in vertically-sliding adjustment, in the present instance by fitting the ends 7 9" to slide on ways r at the ends of the board. The rule is adjusted by means of a cord or wire attached to the ends of the rule and operated to simultaneously move the said ends in the same direction, as follows: A supporting-bracket S is fixed to the rear lower central portion of the board and 4 asri carries a short Vertical axle s, on which is mounted a worm-wheel s, the hub s of which has mounted thereon a segment 8 provided with an operating-levers. The worm-wheel is held in longitudinal adjustment on the axle s by means of a key or nut 8 and the hub s is screw-threaded to receive an adjusting-nut 8 preferably made large enough to be grasped and operated by the hand, which nut bears against the hub of the segment 5 and serves to lock it to and release it from the worm -wheel, as may be desired, The worm-wheel s is operated by a worm s? on a shaft 3 provided with a hand-wheel s for turning the shaft, and hence the worm and worm-'wheel,to operate the segment when the latter is locked to the worm-wheel.

The segment is provided with a pair of angle-levers s one on each side, fulcrumed of one of the levers-for example, s the wire T extends across the curved face of the segment and thence to a guide-pulley r at the lower portion of one of the ends of the board, thence up along the end of the board where it is attached to the end 0'' of the rule, thence over a guide-pulley 4- at the top of the board, thence down and around a guidepulley 1", here shown as concentric with the guide-pulley r thence along the lower portion of the board to a guide-pulley r at the opposite end of 'the board, thence up along the end of the board where it is attached to the endr of the rule, thence over a guide pulley Wat the top of the board, thence down around a pulley r here shown as concentric with the pulley 1' and thence across the curved face of the segment 3 to the short arm of the opposite lever to which it is attached. When it is desired to set the rule to read any line of the pattern, the rule may be quickly raised or lowered to a point near its desired position by releasing the segment vide for this by causing a pointer to travel across the pattern step by step under the control of the feed mechanism, as follows: At or near one end of the pattern-board there is mounted a vertical shaft U in bearings projecting rearwardly from the board, and on a squared portion of the shaft U there are located two disks u u, of equal periphery and preferably a distance apart corresponding to the distance between the two parts R R of the double rule. The disks u a are caused to slide up and down with the rule by means of a bracket U. A cord V, secured at one end to the face of the disk it, extends across the face of the board Q to the periphery of a. spring-actuated wheel W at the opposite end of the board, also arranged to move up and down with the rule, and is wound around the said wheel a sufficient number of turns or fractional part of a turn to permit the cord to be drawn from the wheel a length sufficient to traverse the pattern. In a similar manner a second cord V is secured at one end to the face of the disk u and extends thence across and thence up and around the periphery of the wheel \/V in the same direction as thatin which the cord V passes around it, so that both cords may be simultaneously drawn with equal speeds from the wheel W by the rotation of the disks it a. An index-finger '0, which may consist of an ordinary pin or needle, may be placed in engagement with either of the cords at the point where the reading of the pattern is to begin. The wheel W may be actuated by an ordinary coil-spring 712, connected at one end with a fixed pin to and at its opposite end with the hub w of a handwheel U13, mounted on the axle w, on which the wheel W rotates. The hand-wheel 10 is locked to the hub of the wheel W by means of a nut Q05, screwed on the end of the axle 10 which serves to crowd the hand-wheel into frictional engagement with the wheelW to bring the latter under the tension of the spring w or to release the hand-wheel from the wheel W to permit the spring to be wound or unwound independently of the wheel W. The shaft U is further provided with a pulley a fixed thereon, the periphery of which is connected by a cord a extending from the pulley a around a guide-pulley 10 with a drive-pulley a on the spring-actuated shaft N, which as the feed-carriage I moves to the rear step by step winds the cord a on its periphery, and thereby rotates the shaft U and disks u u thereon to draw the index-finger v on either of the cordsV V step bystep across the pattern, at the same time winding the spring which actuates the wheel W, so that when the feed-carriage is returned to the front and the cord a unwound from the pulley a the wheel W, under the tension of its actuating-spring, will wind the cords V V on its periphery and return the index-finger to position.

The length of the step which the index-finger travels may be varied to suit patterns having the cross-lines at different distances apart by changing the drive-pulley a for others of greater or less diameter. the pulley it being for this purpose made readily removable from the shaft N in any well-known or approved manner.

For indicating to the operator the position.

of the card where each punching operation takes place on the card being punched, I lead a cord V from the front of the carriage to and around pulleys V V at the front of the pattern-board and provide the opposite end of the said cord with a weight V for keeping the cord taut and causing it to travel over the pulleys V V when the carriage is returned. On this cord an index needle or finger of any well-known or approved form maybe placed in such a manner as to travel along a sample card (not shown) placed at the bottom of the board in front of the operator and having thereon the full number of transverse lines of perforations which the card will contain. In operation, at each punching operation the index-finger will be moved by the movement of the carriage a step from one transverse line of perforations on the card to the next, and hence give the desired information.

Boxes X and X are located at the right and left of the table a as the operator faces the machine for receiving the blank cards and the punched cards, respectively.

In the foregoing description I have referred to the shaft N as spring-actuated, and in practice I prefer to use a spring in connection with the special means for regulating its tension; but I wish to be understood in using the term a spring-actuated to include the use ofa wei huwhich in many instances is considered, generically,the equivalent ofa spring and which may obviously be utilized in my present structure withoutrequiring any considerable modification.
